2 BUT.. first a history lesson??
Wild Bill Hickok Are there new invasive fish coming to North America? Dave MacNeill, NY Sea Grant

3 Understanding risk and uncertainty with a deck of cards??
The uncertainty: What poker hand will I draw next? The Dead Man’s Hand: unlucky for Wild Bill Hickok? The risk: What is the probability of drawing it? (<1%)

4 Probability Distribution of Winning Poker Hands

5 But, the card deck changes… unexpectedly……
Death cards Other cards The Risk ?

6 Most recent invasive species are ship “stow-aways” in ballast tanks

10 Phase 1: Identification of potentially invasive Ponto-Caspian fish

11 10 fish species identified as invasion risks to North America
2 GLRI studies: assessment of invasion risk of Ponto-Caspian fish. Russian Literature translation: information on 42 Ponto-Caspian fish; 28 species have invasion potential. Multivariate statistical models: discriminant analysis. Confirmed invasive risk assessment: 5 previously ID’d species (Kolar and Lodge 2002) , ID’d 5 additional potentially invasive species. Of the 10 species: 4 high invasive potential; 4 moderate invasive potential; and, 2 low invasive potential; based on ability to survive ballast water transport. Also ID’d GL indicator species with similar life requirements to potential invaders.

15 Kilka/Tyulka/Black Sea Sprat - Clupeonella cultriventris.
Invasion risk Members of the herring family. School in open waters of rivers, lakes and brackish areas. Can migrate into freshwater to spawn or adapt to freshwater. Food: zooplankton, freshwater shrimp, small fish. May compete with larval fish for food. Use canals/ streams to invade lakes, rivers and reservoirs, “Crowd out” native fish, especially smelt and whitefish. Grow to 5-6”, live 3-6 years. Produce 30,000 to over 100,000 eggs per female.

16 Caspian Sea Kilka - Clupeonella (cultriventris) caspia.
Newly ID’d as high risk to North America; not Great Lakes? Like Kilka, related to “sprats”. May either be a subspecies of the Kilka or a separate species?? Very similar to the kilka in form and habits. Higher salinity tolerance than kilka Slightly shorter (3%) pectoral and pelvic fins than kilka More common in the Caspian Sea area Found as much as 40 miles upstream in rivers that flow into the Caspian Sea. Produce 120, ,000 eggs Jan Porinchak All art work is copy written and may not be used or duplicated without permission from NY Sea Grant

Newly ID’d as invasion risk to North America; Great Lakes? A “shad”: alewife relative, Native to open waters of the Black Sea. Has a saw-like belly like alewife, but no dark spot behind head. Similar to kilka species, but has a notch in upper jaw and teeth. Habitat: cooler, deeper water than alewife in in brackish and saltwater. Spawns in freshwater during spring and summer. Food: small fish, freshwater shrimp. Generally 6-8” in length. Can produce over 300,000 eggs.

19 And now, some really boring information on “herring” taxonomy

20 Some Familiar “Herrings”
Family Clupeidae Subfamily Alosinae Genera: Alosa (shads); Brevoortia (menhaden). Subfamily Clupeinae Genera: Clupea (“true herring”); Clupeonella, Sprattus (sprats); Sardinops, Sardinella (“sardines”); Sardinia (pilchard-”true sardines”). Subfamily Dorsomatinae Genera: Dorosoma (gizzard and threadfin shads). Family Engraulidae Subfamily Engraulinae Genera: Engraulis, Anchoa (“anchovies”). Whitehead (1988) FAO 125 (7) :1

21 Eurasian Minnow- Phoxinus phoxinus.
Use: bait species, stocked as a forage fish, sold in the aquarium trade. Habitat: cold, well oxygenated streams, rivers, lakes in shallow rocky areas. Compete with young trout; can reduce trout abundance by 35%. Food: algae, plant debris, aquatic insects, and mollusks. Variable life histories: life spans, growth rates, egg production, egg sizes, size/age at maturity, spawning behavior and coloration patterns. Reach 5” in length, can live 3-5 years, up to 10 years. Egg production: ,000 eggs. Jan Porinchak Breeding male Jan Porinchak All art work is copy written and may not be used or duplicated without permission from NY Sea Grant

22 Black Sea Silverside (Big Scale Sand Smelt) Atherina boyeri.
High invasion risk to Great Lakes Not a true smelt; related to native silversides in the Great Lakes. Broad salinity range from freshwater to full strength sea water. Tolerates a wide range of temperatures from 32 to high 80 F. Forms dense schools, in still or slow flowing water over vegetation. Food: worms, mollusks, fish larvae, larval insects, small zooplankton. Reduce zooplankton density to low levels. Mature early in life, batch spawner. Batch spawner; March-October; “hairy” eggs. Max. size 3”. Jan Porinchak Jan Porinchak All art work is copy written and may not be used or duplicated without permission from NY Sea Grant

23 Eurasian or European Perch- Perca fluviatilis
Very similar to native yellow perch in body form and habitats. Only physical differences: small (pre dorsal) bones along spine and dorsal fin. (See below) May interbreed with yellow perch. Lives in lakes and some mildly brackish areas (up to ppt) Food: invertebrates and fish. Both species reproduce in freshwater. More tolerant to productive, nutrient enriched waters than yellow perch. Tolerates water temperatures to high 80s and low 90s. Used in the aquarium trade, fillets are also imported to North America.

Invasion history for many inland reservoirs. Males incubate eggs in external brood pouch. Anchors to submerged vegetation to ambush prey. Food: (suction tube mouth) larval fish, small, bottom- dwelling invertebrates. Produce several broods of young over the year (spring to fall). Can spawn soon as 8 days following the previous spawn. Lives up to 4 years, reaching 8”. Jan Porinchak

26 Monkey Goby – Neogobius fluviatilis

30 Results of this study: Invasion success
Introduction/ballast transport: broad salinity tolerances across all life stages. (>.28 ppt). Establishment: higher growth rate and invasion history. (79%)* Spread: lower growth rate and salinity tolerances. (81%)* Negative impact: invasion history, smaller egg size, lower minimum temperature tolerance. (73%)* Life history/ecological characteristics (at each stage of invasion): not always compatible. * Cross validations : Predicted invasions vs. actual invasions Snyder, Burlakova, Karatayev, MacNeill (2014)

41 и в заключение…and in conclusion
ID’d 10 species: 4 high potential, 4 moderate potential, 2 low potential invaders. Statistical risk assessments very useful in screening organisms. Good predictability! Consider stages of invasion process: (introduction), establishment, spread, impact Life history/ecological characteristics at each invasion stage not always compatible. Species with highest salinity tolerances (> 28 ppt) across all life stages most likely to survive ballast exchange. BUT, overall likelihood new ballast-borne invasions is lower because of ballast exchange. Next steps: Develop “watch lists” for high risk species. Monitor preferred habitats/presence of indicator species. Develop eDNA tools for potential invasive species and indicator species. More information needed on natural densities of life history stages/tolerances. Obtain voucher specimens from Ponto-Caspian region.
